Water Catalysis in the Morita–Baylis–Hillman Reaction: A Mechanistic Perspective

Isotope exchange reaction in tritium-contaminated vacuum pump oil: mechanism and HTO effect

“…11,12 In order to discuss the differences with one or two HTO molecules present in the reaction system and interpret the impact of HTO, the energy decomposition analysis (EDA) of this process with one or two HTO molecules was performed.…”

A new class of PN3-pincer ligands for metal–ligand cooperative catalysis

“…A reasonably low transition state barrier would require the H δ+ to reach the electron lone pair of N of the imine arm. Proton-transfer (H-transfer) shuttles were recently identified in facilitating various H-transfer processes in related reactions [58,[97][98][99][100][101][102][103][104][105][106][107][108]. The mediating agents for the H-transfer process can be protonic solvent molecules (alcohols and water), substrates, or products.…”

Amino acid ionic liquids as catalysts in a solvent-free Morita–Baylis–Hillman reaction

“…In this new reaction condition, the MBH adducts were formed, aer 5 hours, in yields ranging from 26 to 44%, Table 3 (entries, [12][13][14][15][16][17], and at signicantly lower reaction times when compared to the reaction times described by Shi and others. As previously discussed, the ionic medium favors a supramolecular organization.…”

“…The deprotonation of the acid group of amino acid was clearly evidenced by 13 C NMR in the signal of carbonyl carbon that has a delocalization to high shi (Table 1). Thermal gravimetric analysis (Table 2) showed that the ionic liquids had a decomposition temperature (T dec ) at $200 C and that the ionic liquids 4a-e had a slightly higher temperature than 5a-e.…”

“…The AAILs structure was conrmed by 1 H, 13 C NMR, infrared spectroscopy (IR), and elemental analysis. The deprotonation of the acid group of amino acid was clearly evidenced by 13 C NMR in the signal of carbonyl carbon that has a delocalization to high shi (Table 1).…”
